Suggestions:
Word in Office 365 has a drawing tab. Use a stylus (digital pen) so that your work is legible. Another option: You can also upload the file to Windows whiteboard and write on the document there. Another option is to use the text box feature for labeling.
If you choose to print out the file and photograph the page, make sure you can convert the file to a pdf. There are many apps that can convert a phone photo to a pdf. Also, make sure the initial photo is sized and positioned correctly. It must be legible.

Building Knowledge
1. Define a diploid cell and a haploid cell.
2. Define a germ cell. Is it diploid or haploid? Where are germ cells found in mammals?
3. Explain the characteristics of a homologous pair of chromosomes.

Application
Review figure 13.8 in the textbook chapter. Use the following statement to answer the application section of the worksheet.
A mammalian germ cell has a chromosome number of 2n = 8
1. Draw the movement to chromosomes during Anaphase I and then Anaphase II. Include in each drawing applicable labels: homologous pair, duplicated chromosome, unduplicated chromosome, centromere. Draw arrows showing the direction of chromosome movement. Do not draw a cell membrane around chromosomes.
Anaphase I Anaphase II
2. Select from the statements below the one that describes the resulting chromosome number in each new cell at the end anaphase I or II, and the completion of cytokinesis during telophase I and II. Add the selection description to the anaphase statements. Do not draw circles with arrows.
2n = 8; duplicated chromosomes; 2 cells
2n = 8; unduplicated chromosomes; 4 cells
1n = 4; duplicated chromosomes; 2 cells
1n = 4; unduplicated chromosomes; 4 cells
After Anaphase I, Telophase I and cytokinesis:
After Anaphase II, Telophase II and cytokinesis:
